Electronic – How does a bare PCB product such as a Raspberry Pi pass ESD testing for CE mark


I am designing a product that is to be sold as a bare PCB as a finished product, and so requires EMC testing to be able to CE mark. I am new to designing for ESD, and protecting every single exposed pin from an 8KV discharge seems overwhelming!

My question is how does something like a Raspberry Pi pass this test? Have they managed to design such that every pin survives 8KV, or am I missing something about how the EMC directive is applied?

Does this answer your question (emphasis added)?

9.3.2 Test method The test method shall be in accordance with EN 61000-4-2 [2]. For radio equipment and ancillary equipment the following requirements and evaluation of test results shall apply. The test severity level for contact discharge shall be 4 kV and for air discharge 8 kV. All other details, including intermediate test levels, are contained within EN 61000-4-2 [2]. Electrostatic discharges shall be applied to all exposed surfaces of the EUT except where the user documentation specifically indicates a requirement for appropriate protective measures (see EN 61000-4-2 [2])
